'Justified' adds Mary Steenburgen to Season 5 cast

Wynn Duffy is now a regular part of the world of
"Justified," and we'll get to know more about him later in the season -- in part via a new character played by
Mary Steenburgen.

The Oscar-winning actress, late of
"Bored to Death" and
"30 Rock," will have a recurring role on "Justified" later this season. She'll make her first appearance in episode 10, FX says.

Her character's name is Katherine Hale, and she's described as a "beautiful Southern belle who was the wife of Wynn Duffy's (
Jere Burns) mentor in crime." How she enters the story remains to be seen.

The first two episodes of "Justified" this season have seen Wynn and Boyd (
Walton Goggins) enter the drug business as Boyd looks for quick cash to help get his fiancee, Ava (
Joelle Carter), out of jail.

"Justified" airs at 10 p.m. ET Tuesdays on FX. What do you think of the casting?
